The Precision Electro-Mechanical Experiments (PREME) program develops precision electro-mechanical measurements for fundamental traceability of the SI units and
Since 1970, the National Institute of Standards and Technology (NIST) has awarded Precision Measurement Grants for significant research in the field of
Since the inception of the SI system of units, physical mass artifacts have been disseminated in order to realize the unit of the kilogram, essential to a broad
Quantum information processing seeks to use the features of quantum physics to accomplish otherwise intractable computational tasks. The two main thrusts of
Graphene, the two-dimensional honeycomb carbon lattice isolated in 2004, has enabled significant advancement in a variety of subfields in physics due to its
The main long-term goals of our theoretical research group are to understand and control large interacting quantum systems, as well as to design and create new
Measurement. Science is rooted in measurement: it is from measurements, as unified by theory, that understanding is born. Our comprehension of the universe is
Quantum nonlinear optics provides a means to generate and manipulate light at the quantum level, with applications in enhanced sensing and metrology, and in
Theoretical work relevant to the determination of values of the fundamental constants, tests of bound-state quantum electrodynamics (QED), and methods of
Practically all measurable physical phenomena are eventually transformed into corresponding electrical representations. The transduction of a signal into its
Physical disassembly of the 4.45 MN (1,000,000 lbf) deadweight machine (DWM) began in FY15 in order to address material galling that developed in key structural
Using a detector capable telling how many photons were received, we explored the potential for enhanced measurement resolution in two measurement applications.
We use light created two photons at a time to explore the time needed to cross a barrier. The extreme simultaneity of creation of the two photons allows for
The small mass and force metrology project at NIST leverages the redefinition of the International System of Units (SI) to scale mass and force with electrical
We develop and learn how to characterize non-classical light sources and single-photon detectors. To have an accurate model of a single-photon detector’s
Interactions between cold atoms can provide us with the means to manipulate matter on the smallest scales. Collisions between laser-cooled atoms, in particular
If quantum computers and networks are ever to be realized, they likely will be made of different types of parts that will need to share information with one
Thermodynamics emerged during the 1800s to describe large, classical systems, such as steam engines, and equilibrium. In contrast, quantum, small classical, and
